Sorry, I did not get it, Pindar. Could you please be more specific?
I know just enough Portuguese (and also know gretl's messages...) to see
that you have an exact collinearity problem, so gretl drops some
arbitrary variables, and this arbitrary choice depends on the ordering.
Or is there more to it? If so, please show us something without the rank
deficiency.
